Megavolt 24, a review
First off, I have to say that I was given the Wolfbox Megavolt 24 to review. Wolfbox in no way at all tried to influence my review. What follows is my honest opinion of the product.
The Megavolt 24 is an all in one jump pack and tire inflator. It is an all in one, so no plugging into the car to power the compressor, which is very convinient.
For the first test, I decided to test the air compressor. I started on my car and deflated the tire down to about 10 PSI. I checked the starting pressure with a quality air pressure gauge. Upon connecting the MegaVolt 24, I was a little surprised to see that it agreed exactly with the analog gauge. I set the desired inflation pressure of 30 P.S.I. and started it up.
While not fast, the unit isn't slow either. A few minutes later the compressor shut itself off. I checked the pressure with the analog gauge and once again, it was spot on. I checked the tires of both our cars and topped up a couple. The battery still read full.
I gave it about 1/2 hour cool down and then I took it over to our van. I deflated one tire down to 10 P.S.I.. The Megavolt 24 took almost 8 minutes to get it pumped up to 60 P.S.I.. By the time it was done the unit was warm and the battery read about 1/2 full. So it will do a 245/75/R16 to full pressure and probably in a pinch inflate two.
After allowing the unit to charge it was time to test the jump pack side of it. I have an 1992 pickup with a V8 that I use a few times a year for things like dump runs or firewood. So the battery is always dead and I just jump start it when I use it. The battery is so old I have no idea when it was last replaced. Since it is an old truck I can disconnect the ignition system and make sure the vehicle doesn't start.
I did 10 cranks of 5 seconds each with 30 seconds in between. No problem. I let the starter cool down for about 10 minutes and then did it again. No problem. Then I hooked the ignition back up and started the truck normally, no problem. The battery still read about 1/2 full.
So, overall it is a great little unit. While it is not an offroad compressor for air down/up, it is perfect for an emergency back up for any vehicle. I'm glad to have it in the trunk of my Subaru and I'm sure it will come in handy.
